In 1 is a rolling bearing cage 1 to see, partially in exploded view, which is composed of the parts as they are in 2 and in 3 are shown.

The cage 1 has a number of webs 4 on, with their two axial ends with side rings 2 and 3 are connected. The side rings 2 . 3 insist on a number of interconnected side ring segments 2 ' . 2 '' . 2 ''' respectively. 3 ' . 3 '' . 3 ''' , Between the bridges 4 lie - from the side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' axially limited - cage pockets 5 for receiving rolling elements (not shown in 1 ), The interconnected side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' form a composite ring structure in the circumferential direction U.

In the solution according to the 1 to 3 is provided that a side ring segment 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' with a jetty 4 by means of a positive connection 6 connected is. Like this positive connection 6 is constructed, results from the 2 and 3 , The side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' have hook-shaped projections in their end regions 6 ' , and indeed - like out 2 visible - two hook-shaped projections 6 ' which protrude once from above and once from below radially. The jetty 4 who in 3 can be seen, each has a recess in the radially outer and in the radially inner Endberiech 6 '' in the form of a groove extending in the axial direction a. The hook-shaped projections 6 ' and the grooves 6 '' are arranged so that the forked end of a side ring segment 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' into the grooves 6 '' can snap into place to find a firm grip. Here are the grooves 6 '' formed so wide that two hook-shaped projections 6 ' in a groove 6 '' Find space, ie the ends of two adjacent side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' abut in the circumferential direction U to each other when in the groove 6 '' are fixed. This is in 1 illustrated. Due to the undercut, the grooves 6 '' for the hook-shaped projections 6 ' form in the circumferential direction U, a firm connection in the circumferential direction U is ensured, especially when the hook-shaped projections 6 ' with the recesses 6 '' form a snap or clip connection.

In 4 is a similar solution to see. The side ring segments used here 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' (S. 5 ) and walkways 4 (S. 6 ) are also here with a positive connection 6 connected. This consists of a thickened in the end region projection 6 ''' which is in a recess 6 '''' can engage with congruent, ie correspondingly matching shape. This connection is designed in the manner of a snap or clip connection, ie when the projection 6 ''' with sufficient pressure in the recess 6 '''' is pressed, this snaps into the recess 6 '''' and thus finds a firm hold.

In 4 can still be seen that at the receiving pocket 5 facing side of the bridge 4 a rolling element guide element 8th is arranged. This serves for improved guidance of the rolling element in the pocket 5 ,

Another alternative embodiment of the invention is in 7 to see. Here is in the end regions of the side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' one loop or noose each 6 ''''' formed having an opening 9 forms, seen in the axial direction a - the cross-sectional shape of the web 4 equivalent. Accordingly, a side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' by pushing in the axial direction a on the web 4 be connected with this. It may be the size of the opening 9 slightly smaller than the cross section of the bridge 4 be selected so that a pressing is required, but then for a firm grip of the side ring segment 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' on the jetty 4 provides.

In 8th is one too 7 alternative, but very similar solution to see. Both embodiments have in common that in the assembled state, the side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' have a complementary shape in the axial direction a, ie, the side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' mounted, results in a substantially undisturbed annular contour through the individual side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' , Accordingly, there are largely undisturbed end faces 7 (S. 7 and 8th ), It should be noted that the design according to 8th something easier to assemble, because in the end the missing side ring segment 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' a fold can be pushed axially, while in the solution after 7 the last two segments must be mounted folded.

Other possible embodiments will be apparent from the others 9 to 16 ,

In 9 to 12 you can see that here are the side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' are slightly arcuate in shape and form in their end region respective hook-shaped projections, both in the adjacent side ring segment 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' as well as in the footbridge 4 engage, each having corresponding congruent recesses for the hook-shaped projections.

In the solution according to 13 and fourteen (the view of the cage according to fourteen in the axial direction a is considered in 16 shown) engage adjacent side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' with a positive connection 6 each other. The webs can 4 from the side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' enclosed and so fixed. The positive connection is here again as a thickened projection 6 ''' formed in a corresponding recess 6 '''' intervenes. In 13 and fourteen are two bridges, by the way 5 between two receiving pockets 5 provided the side rings 2 . 3 connect.

In the solution according to 13 may optionally be provided that the webs 4 be attached by material connection, ie, for example by sticking. The form fit 6 secures the connection between the side ring segments.

Another alternative is in 15 illustrated.

For the individual parts of the cage 1 can be used in large numbers prefabricated components. Particularly preferred is the use of a strand profile produced for example by extrusion for the webs 4 where the required length of the bridge 4 is cut to length from an endless profile. The costs for the cage production are thereby correspondingly low.

Two other variants of the proposed cage are in the 17 to 20 and 21 to 24 shown, each one the cage 1 ( 17 and 21 ) and in the others 18 to 20 respectively. 22 to 24 Details of the same.

The bridges 4 Here are made of sheet metal, with a metal strip was bent so that two equal legs 4 ' and 4 '' result, each extending in the axial direction a. The individual side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' the side rings 2 and 3 are each with a crank 15 provided (s. 19 and 23 ), which produces an axial offset x. If the individual side ring segments are placed against each other, this results in a largely undisturbed ring structure.

In the solution according to the 17 to 20 Every jetty has it 4 in its two axial end portions depending on a passage section 11 , However, the side ring segments have 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' in its two end regions - seen in the circumferential direction U - recesses, which may be produced for example by a stamping process. At assembly of a cage 1 are each two side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' with their recesses 10 on a jetty 4 and especially on its passage section 11 pushed axially, so that there is a situation as in 20 is illustrated.

There is a contact surface for this 12 (S. 18 ) in the axial direction a at the web 4 provided so that the side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' only up to a defined axial position axially on the web 4 can move. The passage section 11 is formed so long that it projects slightly beyond the top side ring segment axially when the assembled state is reached. For the purpose of producing a solid, non-detachable composite, the passage section has 11 in its axial end region two securing sections fourteen on, which are aligned during assembly with the web contour in the axial direction a. Are the side ring segments 2 ' . 2 '' . 2 ''' . 3 ' . 3 '' . 3 ''' Meanwhile, the fuse sections become fourteen deformed, as is in 20 you can see. This results in a form-fitting, solid composite of the webs and the side ring segments.

Very similar to the solution according to the 17 to 20 is the cage 1 according to the 21 to 24 built up.

Here are axial contact surfaces 12 ' . 12 '' through free axial ends of the webs 4 or their thighs 4 ' . 4 '' educated. Otherwise corresponds to the structure of the solution according to the 17 to 20 ,

The cage according to 17 to 24 is preferably made of sheet metal, the required parts are made by punching and forming operations. The in the 17 to 24 shown embodiment for cylindrical roller bearings can be performed with appropriate deformation of the components for tapered roller bearings. Furthermore, the Ver Bonding of the webs and side ring segments not only alone by positive engagement but also be backed by material connection, z. B. by laser welding / soldering / gluing.

The advantage of the last-mentioned solution according to the 17 to 24 lies in a material saving compared to the conventional production of a cage. Furthermore, the solution offers a variable possibility to design the web element shapes. Finally, this embodiment also offers the possibility of assembly and disassembly on site, which z. B. is advantageous in wind power applications.

In the 25 to 28 is another construction concept of Wälzlagerkäfigs illustrated with a special training. Here is the bridge 4 not - as above - from a single component, but the bridge 4 is made of two bridge elements 16 and 17 composed.

In the embodiment according to 25 and 26 consists of the first web element 16 from a (solid) rod with a defined cross-sectional shape; Preferably, the first web element 16 made of metal. The first web element 16 is with its two axial ends with the side rings 2 . 3 or the side ring elements connected. Before attaching the axial ends of the first stake element 16 with the side rings 2 . 3 or the side ring elements is on the first web element 16 a second web element 17 deferred, as is the case in particular 26 is illustrated. For this purpose, the second web element 17 a recess 18 whose cross-sectional shape is that of the first land element 16 equivalent.

The axial length in the direction a of the second web elements 17 corresponds to the desired axial length of the receiving pocket 5 for the rolling elements 23 ,

Accordingly, it is provided that the webs 4 from the first web element 16 and the second web element 17 exist, wherein the second web element 17 with the first web element 16 is positively connected.

This positive connection can also be done in the way it from the 27 and 28 evident. After that is a snap connection 19 provided with the two web elements 16 and 17 be positively connected with each other. The snap connection 19 has two handle sections 20 and 21 on, the second bridge section 17 are formed, which laterally around the first web element 16 be snapped or clipped. Accordingly, the second web members 17 in 28 in the direction of the arrow on the first web elements 16 deferred, with the snap connection 19 a positive connection between the two web elements 16 . 17 will be produced.

An improvement in the mounting of the mounted rolling elements 23 can be achieved if continue on the second web element 17 one or two snap lips 22 are molded or attached, which has a holding function on the rolling elements 23 exercise.

As further exemplarily in 28 can be seen, have the rolling elements 23 a slightly larger diameter (see the registered value of 34 mm) than the clear width between two webs 4 or second web elements 17 (see the registered value of 33.8 mm). This can be achieved by elastic expansion of the webs during assembly of the rolling elements 23 their snapping into the receiving pocket 5 respectively.

As mentioned above, between the first web elements 16 and the side rings 2 . 3 an (additional) cohesive connection are provided, for. B. by welding.
